Answers

Answer 1

Answer:

michelle is 56 years old

Step-by-step explanation:

start with madeline you know she's 7, move on to fiona we know she is twice as old as madeline so we mulitply 7 times 2, we get 14. now we know fiona is 14 and in order to find michelles age we multiply times 4 because shes four time fionas age. 14x4=56.

Answer 2

Fiona is 2x as old as madeline

madeline is 7

A penguin 10 feet in 5 seconds. At this speed: How long does it take the penguin to walk 52 feet?

Answers

Answer:

26 seconds

Step-by-step explanation:

If we want to find out how long it takes to walk 52 feet, we should start by figuruing out how long it takes to walk 50 feet.

10 x 5 is equal to 50

It takes 5 seconds to walk ten feet, and 5 x 5 = 25

Then, because 2 is 1/5 of 10, find 1/5 of 5, which is 1

Add 1 to 25 and you have your answer.
